Specification of Letters Patent.

Patented Dee. e 1, 1907".

Application iiled December l5, 1906. Serial No. 348.067.

To all whom it may concern:

Be it known that I, SAMUEL F. DUTToN, a citizen of the United States,residing at Detroit, county of Wayne, State of Michigan, have invented acertain new and useful Improvement in Nail-Driving Tools, and declarethe following to be a full, clear, and exact description of the same,such as will enable others skilled in the art to which it pertains tomake and use the same, reference' Vduit having a contracted nozzlethrough which there is a guide passage and a plunger with a body partthat hlls the conduit and a contracted hammer terminal that correspondsin size to the nail guide through the nozzle.

In the drawings :'-Figure l, shows a longitudinal section of the tooland the plunger is in elevation. Fig. 2, is a plan view of the nailmagazine. Fig. 3, is a perspective of the nail magazine.

The tool consists of a tubular member l, which terminates at thedelivery end with a nozzle 2, through'which there is an opening 4 forthe passage of a single nail. The bore of the tube l, is large enough toreceive a strong driving plunger 5, sufficiently ,rigid to withstand theordinary forcing strain necessary to drive it into the guide; the stemof the plunger terminates at its driving end with a hammer point 6 thatcan engage closely in and iill the opening 4 through the nozzle. Thechamber of the main part of the tube contracts to the opening throughthe nozzle and the walls of the nozzle within the chamber are properlyinclined to produce a contracting channel that guides withoutobstructing the nail in passing from the larger part of the chamber tothe smaller or nozzle art. p A feed passage 7, for the introduction ofnails into the chamber S is cut through the walls of the tube 1. i Theaxis of the feed passage is inclined to the long axis of the chamber 8.Surrounding the guide 1, at the feed hole is a somewhat funnel shapedmagazine for the reception of a quantity of nails. 'l he Walls of theshell 9 of the magazine are grooved with each groove of a depth toreceive a single nail. Within the bell mouth opening of the shell part 9of the magazine and on the guide l. is a collar'lO with inclined surfacethat projects into the mouth of the magazine g between the shell andthecollar are a number of tubular passages, each of which is formed by agroove II, and that 'part of the collar 10 which is opposite the groove.The magazine is rotatable on the tube and is held up against the collarby a spring l2 which engages between the bottom of the magazine 9 and acollar I3, on the tube l. The bottom of the rotating part of themagazine is provided with notches after the fashion of a crown-ratchet,in which engages the end of a spring 12, that is secured from rotationby a rivet or pin 14, which holds it to the collar 13; the spring aidsthe operator in holding the magazine in proper position to bring a nailcontaining groovein the shell into register with the passage through thewall of the tube into the guiding chamber.

I/Vhat I claim is In a nailing tool, in combination with. a.

tubular guide having its lower end contracted to form a deliverypassage, a driving plunger adapted to be reciprocated therein, its lowerend being complementary in size and contour to the delivery end of theguide piece, a fixed collar engaging about the guide member immediatelyabove a downwardly inclined aperture in the walls thereof, and amagazine member rotatably mounted upon the tubular guide and adapted tocooperate with said collar and the adjacent aperture in the delivery ofnails into the interior chamber thereof one at a time, substantially asdescribed.

In testimony whereof, I, sign this specific ation in the presence of twowitnesses.
